My station recorded a new all-time gust of 65mph
My Fine Offset anemometer peaked this morning at 62.1 mph at 07: 31 and then peaked again at 53 mph at 09:11, I'm quite a bit (sort of) south of you. I was very impressed by Cumulus 1's display screen which has varied the wind speed dial scale throughout the day as the gusts varied.

I've only been recording here for less than a month, so I cannot back up claims by BBC Weather that this was worst storm for 7 years.

Earlier, in a strong gust soon after I put my mast up, the rain gauge blew off. I'm glad to say my whole (repaired) installation withstood the prolonged gales today, nearly everything else in my garden moved from front to back in the prevailing south-westerly, although I'm not aware of any building damage in my village.

12mm of rain today with yesterday's 19 mm has filled the brook with much fast flowing muddy water, threatening to flood some village gardens. (Of course last Autumns rain was nearly every day and caused lots of flooding). My front garden had sitting surface water this morning. Ironically, I am working on installing new plastic underground drainage bought recently in a local store with 10% discount event, but between showers yesterday I did not get very far (just replacing portion where tree roots had blocked old clay pipe) and today was not suitable for more trench digging!

I've uploaded a high resolution radar snapshot of the LEWP at 11:25am. Rain rates of around 200 mm/hr as well as a hail core.

@sfws, you’ve done well to capture such a high gust when the FO only grabs wind every 20 secs or so. It was the strongest gust since 2015 for me.

The rain was almost incidental today as was the temp of 12°C at 11:00 before the squall line arrived. No rainfall rate records broken here.

@Mapantz, thanks for that. I’m right under that intense white area. But just 4 miles away in Wilmslow Mark recorded a gust of around 46mph and missed the worst of it.

Lowest pressure tonight: 959 hpa.
Old record from january 2015 was 966.

They say on the radio that this low pressure makes problems for air traffic. Planes cannot take off because the altimeter can not be trusted when the pressure is too low.

Thanks to Storm Ciara I had my highest ‘wind run’ figure yesterday in 10 years of running Cumulus, 197.3 miles.
Also had the highest ever pressure reading last month, 1049 hPa on the 19th Jan.

Crikey! How different our two locations are. My highest is 432.3 back on 31/3/2015. I'd be interested to know your figure for that day.

My wind run record was broken on 9th Feb 2020 with 439 miles.

Top 5 since 2014

9/2/2020 439
1/3/2018 395
5/12/2015 382
2/3/2018 365
17/3/2018 339

March 2018 was certainly a windy month, on the eastern side of the Pennines, anyway.

My wind run on 9 Feb was 477.4 miles. My (from former Maplin as spare part item number N76NF) Fine Offset annemometer is about 9 metres above ground level on a pole attached to the gable of my garage, so it is not quite as high as official wind measurements, nor is it higher than surrounding houses and trees (although those are several metres away). (As my previous post said, it is a new site, so I can't give previous year comparisions).

As I type this at lunchtime on 15th Feb, Storm Dennis has only just reached here, with 50.6 mph gust at 12:26; it so far seems more peaceful than Storm Ciara, that previous storm bought a tree down to block a nearby road as well as what I reported before. This time nothing significant in my garden has been shifted, but the snowdrops are definitely nodding!
As for the rain, this time it is basically continuous drizzle here, I don't need a coat to go outside, the front garden again has sitting water (because the ground is fully saturated), but the new drainage pipe is working (as far as I got with it).

It might be even more impressive as a posting on the WX forum (http://www.wxforum.net/index.php?topic= ... #msg278935) suggests that the Fine Offset microprocessor inside the transmitter, reads wind data for 8 seconds, ignores it for 8 seconds, reads it again the next 8 seconds, and then repeats those 3 actions once more within the 48 seconds, presumably because the microprocesser is decoding temperature and humidity readings when it is not reading wind data. Every 48 seconds it transmits back to the console the highest of a 2-second reading, and an average of all the readings.

Equalled my gust record of 54mph again. Wind speed managed 29mph. A window of opportunity between 5am and 7am to beat the record when the LEWP moves through here.
My wind run record from last week was 511.8 miles. I'm on 383 miles at the moment.

Postscript to my previous post.
The continuous drizzle I mentioned of yesterday morning changed to very heavy rain around midnight, peaking at 21.6 mm (almost a whole inch) per hour at 23:46 if the Fine Offset has reported correctly. Some of the village was flooded when everyone had gone to bed!
The overnight flood just reached my front door sill, but the house across the road that had put flood gates in front of its front door and garage door, is rather lower than me and despite those defences, it was flooded to a depth of 6 inches downstairs, the loss adjuster is visiting today.
My new drain seems to have worked, my front and back garden are both waterlogged but neither has any surface water. In contrast the front garden of my neighbour on one side is still under water over 12 hours after the storm peak. The neighbour on the other side is slightly higher than my property and their garden is dry.
